These devices are mass produced and made with some tolerance. The spindles are not perfectly balanced and that's what causes the vibration. Since the disks are also mass produced, they add to the off-balance situation.
Some models are worse than others in this respect, but even the better quality models sometimes have the odd noisy drive from a production run.
Wear and tear will eventually add to this as bushes and bearing wear down, so a drive that's seem a lot of use will likely be more problematic and eventually fail to read and write correctly.
You should also avoid using stick-on labels on your disks as it is virtually impossible to put those labels on so that they're perfectly centred.
